Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to a double-angle double-rod inclined-lift demolding mechanism for an upper trim panel mold of an automobile door panel. Background Technique

[0002] The upper trim panel of an automobile door panel is generally formed by injection molding. When injecting the upper trim panel, holes and trim panel support structures with different demolding directions need to be formed simultaneously on the outer side of the upright part of the upper trim panel. Since the forming structures of this part overlap in position on the lower template, in the prior art, the two structures cannot be directly formed by injection molding, and only one of them can be selected, and the remaining structure is completed by secondary processing later, resulting in low production efficiency.

[0003] For example, a Chinese patent discloses a precision injection mold for an upper trim panel of an automobile rear door [Application No.: 202221986827.0], which includes a fixed mold and a movable mold; the fixed mold includes a fixed mold base plate, a hot runner base plate, and a fixed template arranged in sequence from top to bottom.

The upper core-pulling slider can form an installation structure in another direction on the outside of the upright part. During demolding, the lower core-pulling slider remains stationary. When the upper template moves upward, it can drive the first inclined driving rod to move vertically upward. The vertical upward movement of the first inclined driving rod can drive the upper core-pulling slider to move away from the upright part, thereby realizing automatic core-pulling of the upper core-pulling slider. After the upper core-pulling slider completes core-pulling, the first driving component drives the lower core-pulling slider to move obliquely downward along the core-pulling seat, thereby realizing automatic core-pulling of the lower core-pulling slider. At this time, the upper core-pulling slider has been separated from the product, so no interference will occur, which can solve the problems of forming and demolding two-angle structures at the same position in the existing technology.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] As Figures 1 - 4 shown, a double-angle double-rod inclined ejector pin demolding mechanism for an upper trim panel mold of an automobile door panel includes an upper template 1 and a lower template 2. Two forming cavities 3 are symmetrically arranged between the upper template 1 and the lower template 2. The forming cavity 3 is composed of a horizontal part 4 and an upright part 5. An end core-pulling assembly 6 is arranged at one end of the horizontal part 4 far from the upright part 5. A double-angle double-rod inclined ejector pin demolding mechanism 7 is arranged on one side of the upright part 5 far from the horizontal part 4. An oil cylinder guiding inner core-pulling mechanism 8 is further arranged at the top of the upright part 5. The oil cylinder guiding inner core-pulling mechanism 8 is arranged in the upper template 1 and on the opposite side of the double-angle double-rod inclined ejector pin demolding mechanism 7. Five inclined guiding inner core-pulling assemblies 9 are further arranged outside the horizontal part 4.

[0027] In the present utility model, two forming cavities between the upper template 1 and the lower template 2 can form two upper trim panel products by one injection molding. The double-angle double-rod inclined ejector pin demolding mechanism 7 can form two structures with different demolding angles on the outside of the upright part at one time and can complete demolding independently, so that the production of the upper trim panel does not require secondary processing at this position, thereby improving the production efficiency of the upper trim panel;

[0028] Secondly, the oil cylinder guiding internal core-pulling mechanism 8 can realize the automatic core-pulling of the inner insert block before the product is demolded. Five inclined guiding internal core-pulling components 9 can automatically realize the core-pulling of the inner insert block during demolding, and the end core-pulling component 6 can realize the automatic end core-pulling during demolding.

[0029] Specifically, the double-angle double-rod inclined ejector demolding mechanism 7 includes a core-pulling seat 10 arranged at the diagonal of the lower template 2 and having an included angle of 45° with the side wall of the lower template 2. The core-pulling seat 10 is inclined and the outer end of the core-pulling seat 10 is inclined downward. A lower core-pulling slider 11 and a first driving component connected to the lower core-pulling slider 11 are slidably connected to the core-pulling seat 10. The inner end of the lower core-pulling slider 11 is connected to the outer side of the upright portion 5. The top end of the lower core-pulling slider 11 is slidably connected to an upper core-pulling slider 12 that is parallel to the side wall of the length side of the lower template 2 and is horizontally arranged. The inner end of the upper core-pulling slider 12 is also connected to the outer side of the upright portion 5. A first inclined driving rod 13 with its top end connected to the upper template 1 is slidably fitted inside the upper core-pulling slider 12. The connection between the inner end of the lower core-pulling slider 11 and the outer side of the upright portion 5 can form an installation structure on the outer side of the upright portion. The lower core-pulling slider 11 can be automatically core-pulled and demolded by being driven by the first driving component. The upper core-pulling slider 12 is slidably arranged on the lower core-pulling slider and has a different angle from the lower core-pulling slider. The upper core-pulling slider can form an installation structure in another direction on the outer side of the upright portion. During demolding, the lower core-pulling slider remains stationary. When the upper template moves upward, it can drive the first inclined driving rod to move vertically upward. The vertical upward movement of the first inclined driving rod can drive the upper core-pulling slider to move away from the upright portion, thus realizing the automatic core-pulling of the upper core-pulling slider. After the upper core-pulling slider completes core-pulling, the first driving component drives the lower core-pulling slider to move obliquely downward along the core-pulling seat, thus realizing the automatic core-pulling of the lower core-pulling slider. At this time, the upper core-pulling slider has been separated from the product, so there will be no interference, which can solve the problem of forming and demolding two-angle structures at the same position in the prior art.

[0030] Specifically, the first driving component includes a first oil cylinder. The first oil cylinder 14 has an output shaft arranged parallel to the core-pulling seat 10, and the end of the output shaft of the first oil cylinder 14 is connected to the lower core-pulling slider 11. The first oil cylinder can drive the lower core-pulling slider to move obliquely downward along a direction parallel to the core-pulling seat.

[0031] Specifically, the oil cylinder guiding internal core-pulling mechanism 8 includes an upper sliding seat 15 fixed inside the upper template 1. A first inner insert block 16 and a first driving slider 17 are slidably connected to the bottom of the upper sliding seat 15. The end of the first inner insert block 16 is obliquely inserted downward into the molding cavity 3 and is connected to the inner side of the vertical portion 5. The first driving slider 17 is horizontally arranged, and the first driving slider 17 and the first inner insert block 16 are connected by a first inclined guiding structure. A second driving component connected to the first driving slider 17 is further provided on the upper template 1. Before mold opening, the second driving component can drive the first driving slider to move horizontally outward. When the first driving slider moves horizontally outward, it can drive the first inner insert block 16 to move obliquely upward in the direction close to the first driving slider through the first inclined guiding structure, so as to separate the first inner insert block from the product. The first inclined guiding structure includes a first T-shaped sliding groove 18 obliquely arranged inside the first driving slider 17. A first T-shaped guiding block 19 inserted into the first T-shaped sliding groove 18 is fixedly connected to the inner end of the first inner insert block 16. When the first driving slider 17 moves horizontally outward, it can drive the first inner insert block 16 to move obliquely upward in the direction close to the first driving slider through the first T-shaped sliding groove 18 and the first T-shaped guiding block 19.

[0032] Specifically, the second driving component includes a second oil cylinder 20. The end of the output shaft of the second oil cylinder 20 is connected to the first driving slider 17. The second oil cylinder can drive the first driving slider to move horizontally.

[0033] Specifically, the inclined guiding internal core-pulling component 9 includes a lower sliding seat 21 fixed on the lower template 2. An obliquely arranged second inner insert block 22 is slidably connected inside the lower sliding seat 21. The top of the second inner insert block 22 is obliquely inserted upward into the molding cavity 3 and is connected to the horizontal portion 4. A second driving slider 23 is further slidably connected to the lower template 2. The second inner insert block 22 and the second driving slider 23 are connected by a second inclined guiding structure. A second inclined driving rod 24 with the top connected to the upper template 1 is slidably fitted on the second driving slider 23. The second inclined guiding structure includes a second T-shaped sliding groove 25 obliquely arranged at the outer end of the second inner insert block 22. A second T-shaped guiding block 26 inserted into the second T-shaped sliding groove 25 is fixedly connected to the second driving slider 23.

[0034] During mold opening, when the upper template moves upward, it can drive the second inclined driving rod 24 to move vertically upward. When the second inclined driving rod 24 moves vertically upward, it can drive the second driving slider 23 to move away from the horizontal portion. When the second driving slider 23 moves away from the horizontal portion, it can drive the second inner insert block 22 to move obliquely downward through the second T-shaped sliding groove 25 and the second T-shaped guiding block 26 to separate the second inner insert block from the product.

[0035] Specifically, the end core-pulling assembly 6 includes an end core-pulling slider 27 slidably connected to the lower template 2. The inner end of the end core-pulling slider 27 is fixedly connected with a third inlay block 28 inserted into the end of the horizontal part 4. The upper template 1 is also fixedly connected with a third inclined driving rod 29. The third inclined driving rod 29 is inserted into the end core-pulling slider 27 and is slidably matched with the end core-pulling slider 27. When the mold is opened, the upward movement of the upper template can drive the third inclined driving rod 29 to move vertically upward. The vertical upward movement of the third inclined driving rod 29 can drive the end core-pulling slider 27 to move away from the end of the horizontal part, so as to realize the automatic core-pulling of the third inlay block when the mold is opened.

[0036] The working principle of the utility model is as follows: Two forming cavities between the upper template 1 and the lower template 2 can form two upper trim panel products by one injection molding. The double-angle double-rod inclined ejector demolding mechanism 7 can form two structures with different demolding angles on the outside of the vertical part at one time and can complete demolding independently, so that the production of the upper trim panel does not require secondary processing at this position, thereby improving the production efficiency of the upper trim panel. Secondly, the oil cylinder-guided inner core-pulling mechanism 8 can realize the automatic core-pulling of the inlay block before the product is demolded. Five inclined-guided inner core-pulling assemblies 9 can automatically realize the core-pulling of the inlay block when the mold is opened. The end core-pulling assembly 6 can realize the automatic core-pulling at the end when the mold is opened.

[0037] The inner end of the lower core-pulling slider 11 is connected to the outside of the vertical part 5, and an installation structure can be formed on the outside of the vertical part. The lower core-pulling slider 11 can be driven by the first driving assembly to realize automatic core-pulling and demolding. The upper core-pulling slider 12 is slidably arranged on the lower core-pulling slider and has a different angle from the lower core-pulling slider. The upper core-pulling slider can form an installation structure in another direction on the outside of the vertical part. When the mold is opened, the lower core-pulling slider remains stationary. The upward movement of the upper template can drive the first inclined driving rod to move vertically upward. The vertical upward movement of the first inclined driving rod can drive the upper core-pulling slider to move away from the vertical part, so as to realize the automatic core-pulling of the upper core-pulling slider. After the upper core-pulling slider completes core-pulling, the first driving assembly drives the lower core-pulling slider to move obliquely downward along the core-pulling seat, so as to realize the automatic core-pulling of the lower core-pulling slider. At this time, the upper core-pulling slider has been separated from the product, and the first oil cylinder can drive the lower core-pulling slider to move obliquely downward along the direction parallel to the core-pulling seat.

[0038] Before the mold is opened, the second driving assembly can drive the first driving slider to move horizontally outward. The horizontal outward movement of the first driving slider can drive the first inlay block 16 to move obliquely upward in the direction close to the first driving slider through the first inclined guiding structure, so as to separate the first inlay block from the product. When the first driving slider 17 moves horizontally outward, it can drive the first inlay block 16 to move obliquely upward in the direction close to the first driving slider through the first T-shaped chute 18 and the first T-shaped guiding block 19. The second oil cylinder can drive the first driving slider to move horizontally.

[0039] During mold opening, the upward movement of the upper template can drive the second inclined drive rod 24 to move vertically upward. The vertical upward movement of the second inclined drive rod 24 can drive the second drive slider 23 to move away from the horizontal part. The movement of the second drive slider 23 away from the horizontal part can drive the second inner insert 22 to move obliquely downward through the second T-shaped chute 25 and the second T-shaped guide block 26, so that the second inner insert is separated from the product. The upward movement of the upper template can drive the third inclined drive rod 29 to move vertically upward. The vertical upward movement of the third inclined drive rod 29 can drive the end core-pulling slider 27 to move away from the end of the horizontal part, so as to realize the automatic core-pulling of the third inner insert during mold opening.
